CLOTHES-LINE PULLEY.

Specification of Letters Patent.

Patented May 30, 1916.

Application'filed September 24, 1915. Serial No. 52,518.

To all whom it may concern Be it known that I, ROLAND E. CHATTA- WAY, acitizen of the United States of America, residing in the borough ofBrooklyn, county of Kings, city and State of New York, have inventedcertain new and useful Improvements in- Clothes-Line Pulleys, of whichthe following is a specification.

' This invention relates to improvements in clothes line pulleys, andaims to provide improvements therein. v

It is the purpose of the present invention to provide an easy runningpulley for clothes lines (preferably ball bearing), in which the runningparts are'protected from the weather, and'which is durable, simple inconstruction, and cheap to manufacture.

Other specific features of improvement will be referred to hereinafter.

The invention will be more clearly described in connection with theaccompanying drawings, illustrating, two embodiments,

wherein I Figure 1 illustrates an elevation of one of the embodiments;Fig. 2 is a bottom plan view of the construction shown in Fig. 1;

. Fig. 3 is an end view of said construction;

Fig. 4 is a vertical cross section; Fig. 5 illustrates a detail of thecasing and bearing; Fig. 6 illustrates a side elevation of a secondembodiment; and Fig. 7 is a top plan view of the constructionillustrated in Fig. 6.

In said drawings A designates the casing of the pulley, which ispreferably constructed of two pressed or cast metal parts or shells a aThe shells a a are conveniently fastened together by means of rivets a Bdesignates the pulley wheel. The wheel is preferably mounted upon ballbearings. The ball bearings preferably comprise a plurality of balls I),a pair of cupped rings 6 forced into recesses on opposite sides of thewheel B, and a pair of cones b 6 The cones b have polygonal bases whichfit within the polygonal recesses b in the inner sides of the shells orparts a a of the casing A. The recesses in the casing position thecones, and prevent them from turning. Moreover, the weight or strain onthe wheel is transmitted through the cones b to the casing A. The conesb ,are preferabl bored and fit upon a shaft 6 the ends 0 which arereceived in recesses b in the parts a a v of the casing A. The shaft 6has shoulders I) thereon spaced the proper distance apart of the cones,and the cones are held in position by the fit of the polygonal ends ofthe in and out of the casing. The tubular openings a and a arepreferably flared outwardly, whereby the rope, even when it sags, w1llnot rub against thecasing, especially the sharp edges thereof.

In cold and wetfweather ice and snow accumulate upon the' rope, and whenthe rope makes a sharp bend, as in passing over the pulley, much of theice breaks and becomes detached from the rope. To prevent this detachedice choking the runway through the casing, an opening a is provided inthe bottom of the casing, through which opening the detached ice mayfall.

An eye a is preferably attached to the casing. This eye servesforattaching the pulley to a support. The eye is preferably provided with ashank a which is tapered and squared and fits in a correspondinglyformed recess a in the casing. The recess a is preferably formed in thetwo parts of the casing a and a partly in one and partly in the other.The tapered and squared form of the shank holds the eye in the casing,closes the recess against the weather, and prevents the eye fromturning. The casing furthermore, may be provided with an opening a, inaddition to the against the shoulders on the spindle on their inner endsare held in position and serve to space the wheel and prevent itshitting the casing.

Changes may be made in the constructions a casing and a wheel withinsaid casing,

said casing having openings for the running in and out of the line, anopening above said wheel and an opening below said wheel through whichparticles of ice detached from the line may fall, and a cover forsaid'upper opening.

3. A pulley comprising a casing and an attaching eye, said attaching eyehaving a squared and tapered shank, said casing having a squared andtapered recess therein in which said shank fits, and said casing havingan opening formed in its lower part.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
